Member Function Documentation
◆ assignValueToAddress()
|
inlineoverridevirtual |
The specified value has been assigned to a stack location.
Load or store it there, with appropriate extension if necessary.
Implements llvm::CallLowering::ValueHandler.
Definition at line 66 of file M68kCallLowering.cpp.
References Addr, llvm::MachineFunction::getMachineMemOperand(), llvm::inferAlignFromPtrInfo(), and llvm::MachineMemOperand::MOStore.
◆ assignValueToReg()
|
inlineoverridevirtual |
The specified value has been assigned to a physical register, handle the appropriate COPY (either to or from) and mark any relevant uses/defines as needed.
Implements llvm::CallLowering::ValueHandler.
Definition at line 59 of file M68kCallLowering.cpp.
References llvm::RegState::Implicit.
◆ getStackAddress()
|
inlineoverridevirtual |
Materialize a VReg containing the address of the specified stack-based object.
This is either based on a FrameIndex or direct SP manipulation, depending on the context. MPO should be initialized to an appropriate description of the address created.
Implements llvm::CallLowering::ValueHandler.
